Hi Vietnam,as a foxhole is fresh dirt I would use gravol from a construction site,when it`s dryed out it makes the best and the most fun to use groundcover. The pathway would be a littlte lighter as it would be dry and hardpacked. Something to remember,
treat groundcover as you would treat your tank or extra gear, hilighted groundcover is just as important as hilights on the faces of your figures,and it will show in the end product. Hope to see pics of how your doing.
